I have noticed a very small drip of oil below my port engine on the outside opposite the starter. I think I can see a little drip on a flat edge towards the back maybe part of the bell housing? Any ideas would be much appreciated. The engines were just put in 65 hours ago. Thanks.

Have you re-torqued bolts or ck them?

Everything was re-torqued at 15 or 20 hours. Is there anything that can loosen over time? This little bit of oil drives me nuts as Im a fanatic about clean.

So this is on the port side of the port engine. Right?

Check the oil sending unit.

Port engine port side rear. I checked around that thought it was ok. I there anything back by bellhousing where a leak could occur?

oil press sending unit. OR
remote filter lines where the oil filter used to be. OR
distributer

Check all the valve cover bolts.

Check the bottom of the bellhousing if its wet could be a rear main. I hope not.

Where does your oil cooler run on the bottm or on the back check those lines too.
